Long Thin Screws: Drawing and Manufacturing Requirements

Custom long thin screws need a drawing that defines more than overall length. Material, shank diameter, head and drive geometry, thread length and straightness requirements all influence the manufacturing route and inspection plan.

Dimensions to include in your drawing

Specify the overall length, thread size and pitch, threaded length, shank diameter, head dimensions, drive type and critical tolerances. Identify any straightness or assembly-fit requirements and the inspection method to be agreed for the part.

Manufacturing review

Shi Shi Tong assesses cold heading, thread rolling, straightening and machining according to the material and geometry. Long and slender parts require particular attention to deformation and the condition after heat treatment or surface finishing. The process and acceptance criteria are confirmed for each design.

Our long-screw product family covers M1.4–M12 diameters and 2–2000 mm lengths, with common long-screw lengths of 200–600 mm. These ranges do not represent every possible diameter-and-length combination; feasibility depends on the material, structure and process.
